T-Bird 1Ghz 266

So I must be a fool or something, I ordered this chip a few weeks ago and when I installed it in a Asus AV7133 it continuly posted as a 750 Mhz. I rechecked my jumpers and there were set for auto, my prefered way of setting these up.

So I called the place and asked for the right one, had to be wrong if it could only post at 750, not 1033...So I next day shipped it back to them so they could send out the replacement ASAP, I didn't care I just wanted my darn CPU...

2 days later I have not received the replacement and called them...they still had it and claimed that this was the proper CPU and that there are problems posting this chip correctly...um, OK, sure whatever...let me try to force it to 1033 Mhz via manual jumper settings...hmm, odd, it will still only post at 750...

SO, is there really a trick to get this to work properly or are they yanking my chain so frigging hard my head is going to pop-off?

I would look at the cpu markings. It should say AMD-A1000 if it is a 1 ghz CPU. If it says anything else then it's probably not a real I ghz athlon. If the chip does say it's a 1 Ghz cpu, then you must be doing something wrong. Maybe disable jumberfree mode and then manually set you multiplyer to 10.0.

It has that marking so it must be good, I've tried to set the multiplier via the BIOS and manual jumpers...what am I missing? I did get the JEN jumper to enable manual settings....

Just a thought...What BIOS are you running? v1004 is the latest one, if you don't have it then flash the BIOS, I heard there were problems with CPU Detection on the earlier BIOS. <IMG SRC="smilies/cool.gif" border="0">

If you have a newer 266 front side bus chip,the multiplier will default to a lower number which is 7.5.A 200mhz fsb chip has a default clock setting of 10.

7.5 x 100 = 750

7.5 x 133 = 1000

Your problem is your front side bus needs to be set to 133,Default fsb is usually 100 and that is why your chip posted at 750.

Thanks Boricuamed and Diehrd, that sounds like what I'm looking for. I'll try Diehrd's suggetion first and if that doesn't work go for the BIOS update. It might already be on the 1004 but I'll have to check when I get home.

THANKS!!
